在gdb中将变量设置为frame的地址？

(gdb) backtrace
#0  main () at example.c:5
#1  0x00005555555551c2 in func2 () at example.c:10
#2  0x000055555555519d in func1 () at example.c:15
#3  0x00005555555551e2 in main () at example.c:20
(gdb) frame 2
#2  0x000055555555519d in func1 () at example.c:15
15          int a = 10;
(gdb) print &a
$1 = (int *) 0x7fffffffe10c
(gdb) frame 0
#0  main () at example.c:5
5           func1();
(gdb) set $a = 0x7fffffffe10c
(gdb) print a
$2 = 10
